为什么犹太人聪明

我试图Telnet设备，可总是连接失败。 在设备上使用tcpstatShow，结果如下： -> tcpstatShow
TCP:
0 packet sent
0 data packet (0 byte)
0 data packet (0 byte) retransmitted
0 ack-only packet (0 delayed)
0 URG only packet
0 window probe packet
0 window update packet
0 control packet
3 packets received
0 ack (for 0 byte)
0 duplicate ack
0 ack for unsent data
0 packet (0 byte) received in-sequence
0 completely duplicate packet (0 byte)
0 packet with some dup. data (0 byte duped)
0 out-of-order packet (0 byte)
0 packet (0 byte) of data after window
0 window probe
0 window update packet
0 packet received after close
0 discarded for bad checksums
0 discarded for bad header offset field
0 discarded because packet too short
0 connection request
0 connection accept
0 connection established (including accepts)
3 connection closed (including 0 drop)
3 embryonic connection dropped
0 segment updated rtt (of 0 attempt)
0 retransmit timeout
0 connection dropped by rexmit timeout
0 persist timeout
0 keepalive timeout
0 keepalive probe sent
0 connection dropped by keepalive
0 pcb cache lookup failed 请教高手，embryonic connection dropped会在什么情况下发生，首先声明我的系统中没有IPSec。 [align=right][color=#000066][此贴子已经被作者于2004-2-10 14:22:57编辑过][/color][/align]
